使用moshi从这个GET调用反序列化有点问题

https://min-api.cryptocompare.com/data/pricemultifull?fsyms=007,1337&tsyms=EUR,USD 结果看起来像这样。

收到以下错误。

com.squareup.moshi.JsonDataException: Required value 'displayMapToCurrency' 
missing at $.DISPLAY.1337

我使用以下数据类包装另一个

//外层

data class FullPriceWrapper(
@Json( name = "DISPLAY")
val DISPLAY : Map<String, FullPriceWrapperInternalDisplay>
)

//中级班

data class FullPriceWrapperInternalDisplay(
   val displayMapToCurrency : Map<String,CurrencyFullPriceDataDisplay>
)

//最内在的课程

data class CurrencyFullPriceDataDisplay(
@Json(name = "FROMSYMBOL")
val FROMSYMBOL: String,
@Json(name = "TOSYMBOL")
val TOSYMBOL: String,
@Json(name = "MARKET")
val MARKET: String)

所以我假设中间类没有在这里从错误消息中实例化？ moshi中是否存在嵌套类的问题？我通过改进创建我的api实例，如下面传递的MoshiConverterFactory。

return Retrofit.Builder()
            .baseUrl(compareApiEndPoint)
            .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
            .addConverterFactory(MoshiConverterFactory.create(moshi))
            .build().create(CryptoApi::class.java)

我还尝试过代码生成注释，为每个类创建适配器，但没有任何乐趣。生成适配器。也许我有错误的想法，但我认为这些是用注释自动生成的？（如下所示）

@JsonClass(generateAdapter = true)

但我认为我目前对图书馆不够熟悉。我想知道是否需要添加自定义适配器，就像我在其他示例中看到的那样？我也试过这个，但我不确定如何从我见过的例子中创建这些适配器？如果有人有关于如何纠正这个错误的想法，这将是伟大的！我也希望这个问题相对准确。谢谢！

非常不确定如何使用moshi反序列化JSON嵌套对象
